CT-guided percutaneous catheter drainage of lymphocele complicating splenorenal anastomosis.

We report the successful management by CT-guided percutaneous catheter drainage of a lymphocele complicating a Warren-Zeppa distal splenorenal venous anastomosis. The early postoperative course of this 31-year-old male with homozygous alpha 1-antitrypsin deficiency was complicated by chylous ascites and a large lymphocele demonstrable on CT scanning. The persistent 10.5 cm diameter lymphocele was drained percutaneously 5 weeks later by a CT-guided catheter. Drainage of lymph continued at decreasing rates for 13 days when the catheter was removed. Complete resolution of the lymphocele was confirmed at 2 1/2 months. The successful treatment of a lymphocele by percutaneous catheter drainage may obviate major surgery and has not been previously documented.
